Across
- 3. electromagnetic energy, travels in waves
- 4. height of wave, determines intensity
- 6. Small adjustable opening in the eye which is surrounded by the iris
- 8. A theory that holds we have 3 types of color receptors
- 9. retinal receptors that detect black, white, and grey; also sensitive to movement
- 10. the location of most of the cones; in the center of the retina; no rods live here
Down
- 1. the distance between two electromagnetic energy wave peaks, determines hue
- 2. the point at which the optic nerve leaves the eye; no receptors are located there
- 5. the nerve that carries neural impluses from the eye to the brain
- 7. retinal receptors that are concentrated near the center of the retina; function in daylight or well-lit conditions
